  • Patent number: 10394369
    Abstract: According to one embodiment, a display device includes a display area with pixels, and a detection electrode which includes first conductive lines overlapping the display area. Each of the pixels includes a first subpixel, a second subpixel adjacent to the first subpixel in a first direction, a third subpixel adjacent to the first subpixel in a second direction, and a fourth subpixel adjacent to the third subpixel in the first direction and to the second subpixel in the second direction. The pixels are arranged in the first direction with a first pitch, and the first conductive lines are arranged in the first direction with a second pitch which falls within a range of 2.2 times the first pitch or more and 3.2 times the first pitch or less.

  • Patent number: 9911791
    Abstract: In a display device, light emitting areas and colored areas each have a predetermined planar shape having no rotational symmetry so that rotation of the area by an angle greater than or equal to 0° but smaller than 360° does not produce an initial shape of the area and are so arranged as to have different types of rotation angle. The colored areas are grouped based on a set of the colored areas of colors different from one another to forma plurality of full-color pixels. The full-color pixels are so arranged that the rotation angle of the colored areas of the same color have different types. In the full-color pixels of the same type, the colored areas of the same color have the same rotation angle. In the full-color pixels of different types, the colored areas of the same color have different rotation angles.

  • Patent number: 9874787
    Abstract: Provided is a liquid crystal display device including a first spacer and a second spacer, which reduces the amount of residual displacement between a TFT substrate and a counter substrate after an external force applied to the liquid crystal display device has been removed, The first spacer, as seen in plan view, has an octagonal shape of a special form with a long axis in a direction of its gate lines, is planar in section at a central section thereof, and includes an inclined section on both sides. The second spacer has an octagonal shape of a special form with a long axis in a perpendicular direction relative to the gate lines, is planar in section at a central section thereof, and includes an inclined section on both sides. A gap between the TFT substrate and the counter substrate is defined by the first spacer and the second spacer.

  • Publication number: 20170250240
    Abstract: Provided is a display device including: a first gate line and a second gate line which extend in a first direction; a signal line and a current-supplying line which extend in a second direction intersecting with the first direction; a first sub-pixel surrounded by the first gate line, the second gate line, the signal line, and the current-supplying line; and a light-shielding film located over the first sub-pixel. The light-shielding film has a first opening portion and a second opening portion, and the first sub-pixel overlaps with the first opening portion and the second opening portion and has an emission region and a light-transmitting region. In the light-transmitting region, a distance in the first direction between the signal line and the current-supplying line continuously changes along the second direction.

  • Publication number: 20090084884
    Abstract: A wheelchair fixing apparatus (2) according to the present invention includes belts (21) having connecting members (23) which can be attached to and detached from fixing hardware pieces (3) installed on a floor and winding devices (22) for winding up and accommodating the belts (21) and the winding devices (22) are disposed on the wheelchair (1). Therefore, the fixing hardware pieces (3) to which the belts (21) are connected through the connecting members (23) suffice as the floor-side equipment. Moreover, with this apparatus, a user of the wheelchair can perform the fixing operation by himself/herself. Even when a caretaker performs the operation, the burden on the caretaker in performing the operation can be reduced. Furthermore, the apparatus need not be carried by the caretaker, nor need it be ready in advance in a place where the wheelchair (1) is to be fixed.
